Fields

session_id: String

route: RuntimeEnvContext

episode_id: String

episode_record_id: String

episode_ids: Vec<String>

episode_record_ids: Vec<String>

step: i64

env_index: i32

is_reset: bool

num_envs: u32

observation_space: Arc<SpaceSpec>

Shared so the per-step, per-hook event fan-out clones an Arc pointer rather than deep-copying the observation space spec on every step. Types observation: when the relay policy converted it into a new layout, this is the converted space and raw_observation keeps the contract’s.

observation: Option<Vec<Bytes>>

Opaque per-leaf wire bytes; the relay is content-blind (§13).

To persist as a single artifact, use rlmesh-grpc’s wire::leaves_to_blob — plain concatenation loses the leaf boundaries, which cannot be recovered for variable-length leaves.

raw_observation: Option<Vec<Bytes>>

The env’s observation before transform_observation ran; equals observation when no transform changed it.

infos: Option<MetaMap>

The env’s reset infos when is_reset; step infos ride on StepCompletedEvent instead.
